I've got a Yamaha 03D which is a really nice unit. I've migrated my Logic rig to my PB 15" but the Motu 2408 is PCI based. Currently my 03D uses ADAT LightPipe to communicate with the PCI Mac. I'm contemplating the purchase of a Presonus FW interface or finding a PB8-mLan card for the 03D. If anyone is using the mLan based interface, I'd appreciate hearing your impressions.
